"A vulnerability in the Internet Key Exchange Version 2 Mobility and
Multihoming Protocol (MOBIKE) feature for the Cisco Adaptive Security
Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD)
Software could allow an unauthenticated, remote attacker to cause a
memory leak or a reload of an affected device that leads to a denial
of service (DoS) condition. The vulnerability is due to the incorrect
processing of certain MOBIKE packets. An attacker could exploit this
vulnerability by sending crafted MOBIKE packets to an affected device
to be processed. A successful exploit could cause an affected device
to continuously consume memory and eventually reload, resulting in a
DoS condition. The MOBIKE feature is supported only for IPv4
addresses.

This plugin only works with Tenable.ot.
